Title: Electrochemical apparatus and process for the manufacture of halates
IPC: C25B9/17
Filed: 1972-09-08
Abstract: 1396357 Electrolytic apparatus for manufacturing a halate HOOKER CHEMICALS & PLASTICS CORP 8 Sept 1972 [5 Oct 1971] 41884/72 Heading C7B Electrolytic apparatus for manufacturing a metal halate, such as NaClO 3 , NaBrO 3  or KIO 3 , from aqueous halide solution comprises electrode structures 16, Fig. 1, (which are shown in more detail in Figs. 3 and 4). Hypohalite is formed between anodes and cathodes 17, 19, Fig. 4, in gaps 21. The electrolyte in the gaps, which also contains gaseous electrolytic products, rises through the gaps and continues upwardly through ducts 25. Hydrogen is removed from the top portion of the cell through an opening 29, Fig. 1. The electrolyte flowing from the top of the ducts 25 then passes downwardly between the ducts 25 through passageways 31, Fig. 1, provided with staggered baffles 33, 35, 37, Fig. 4. While passing downwardly, the hypohalite is converted to halate. The halate solution can be removed from outlet 42, Fig. 1, and fresh halide solution added through nozzles 46, 48. The anodes 17, e.g. in the form of solid sheets, perforated or expanded metal, may be of valve metal coated with noble metal (i.e. Ru, Rh, Pd, Os, Ir, Pt, Ag or Au) or a noble metal oxide. For example the anodes may be of Pt, Pt-Ir or Ru oxide over Ti, Ta or Nb. They are mounted on plates 53, Fig. 1, forming parts of the structure of a side of the cell and are removable through this side. The cathodes 19, e.g. of Fe or steel, are mounted on the opposite side of the cell. A pair of cathodes 19 is spaced by bars 79, Fig. 4, and surrounded by polymeric cords 93, Fig. 3, located in grooves in the cathode surface. The cords space the cathodes from the adjacent anodes. The mounting of the anodes is by means of conductors 47, a conductor being secured both to the anode and to a plate 53 and passing through the plate Fig. 6 (not shown), e.g. for electrical connection to another cell. At their opposite ends the conductors are spaced by members 66 and 77, Fig. 1. The lower portion 15 of the cell is of steel with the cathodes in electrical connection therewith. The plates 53 which carry the anodes are secured to but electrically insulated from this portion. The upper portion of the cell is of fibreglass reinforced plastics and is reinforced by channels 117 filled with foam plastics. There may be heat exchange means in the anodes, cathodes, or cell top. Further, there may be heat exchange through tubular (instead of rod) anode connectors or through anode reinforcing channels or through heated baffle or partition walls 36, Fig. 4. Electrical connection between cells is by bowed members (129, 131), Fig. 2 (not shown) which are able to take up movement caused by expansion and contraction of cell parts.

Abstract: 1,194,342. Aerials. STANDARD TELEPHONES & CABLES Ltd. 14 Sept., 1967, No.41988/67. Heading H4A. A frequency scanning aerial array comprises aerial elements 1 arranged on a common axis, Fig. 1, or, parallel, Fig. 4 (not shown), axes, each element having a periodic series of discontinuities in its wave-supporting structure arranged so that the angle between the radiated wave and the direction of propagation within the aerial structure is dependent on the frequency of the energy feed and each element being constructed for maximum radiation efficiency at a different frequency to that of the other elements, a variable-frequency source 3, and a band-pass filter 2 for each element and arranged to pass energy to the associated element within only a limited frequency range corresponding to the frequency at which the element is most efficient. An element may consist of a layer of ceramic dielectric material backed by a sheet of copper and grooved transversely to the wave propagation direction, Figs. 2, 3 (neither shown). In the parallel-axes arrangement the spacing between adjacent elements is #/2n, where # is the free space wavelength at the highest frequency and n is the number of elements.

Title: Improvements in or relating to the manufacture of junction transistors
Inventor: LEE MICHAEL ADRIAN
IPC: H01L21/00
Filed: 1958-12-31
Abstract: 906,060. Transistors. GENERAL ELECTRIC CO. Ltd. Dec. 11, 1959 [Dec. 31, 1958], No. 42194/58. Drawings to Specification. Class 37. A method of manufacturing a junction transistor incorporating a germanium element having an N-type base region includes the steps of forming a P-type emitter region in the element by an indium or indium-germanium alloying process in which the maximum temperature reached by the molten material is greater than 650‹ C., preferably 700-850‹ C., and then forming a P-type collector region in the element by a second indium alloying process in which the maximum temperature reached by the molten material is not greater than 600‹ C. The molten alloying material can be produced in situ by fusing a solid body of the material in contact with the germanium element, or the alloying material may be melted separately and applied to the germanium element in the molten state. In the formation of the emitter region a heat cycle in a reducing atmosphere can be used, the heat cycle consisting of heating to a temperature of 800 C. at a rate of about 180‹ C. per minute, maintaining it at this temperature for a few minutes, and then cooling it to room temperature at a rate of about 90‹ C. per minute. In the formation of the collector region a heat cycle is used which is similar to the first except that the maximum temperature is 550 ‹ C. The above procedure produces indium emitter and collector electrodes. The formation of the collector region takes place on an apertured nickel plate tinned with a soft solder to produce the base electrode of the transistor. The transistor so produced is subjected to a process of etching to remove surface contamination and is then mounted in a hermeticallysealed envelope through which are sealed leads for the three electrodes.

[Also in Division B6] In a machine for sealing overlapped portions of a metal strap S, Fig. 10 (see Division B6), the strap is pulled from a supply roll (not shown) around a box or package (not shown) with the free end of the strap underneath the portion adjacent the supply roll. The free end of the strap S is passed under guide 52 and under gripper bar 62 held upwardly by manual pressure on a flange 72 of a lever 64. The free end of the strap is positioned over a knurled pad 51, Fig. 8, and the lever 64 is released to hold the strap against movement. The overlapped portion of the strap is moved laterally over the bar 62, Fig. 10, and through notch 113, such that the overlapped portion passes between the free end and a tensioning wheel 44, Fig. 8. An operating lever 187, Fig. 14 (not shown), is depressed to lower an air supply valve 172 which is then latched in lowered position. A pin 144, Fig. 6, releases a motor latch 31 to allow a spring 37 to raise motor housing 27. Knurled wheel 44 is moved downwardly while being driven by the motor. The strap S is thus tensioned around the box or package until the motor stalls.. Depression of a lever 207, Fig. 14 (not shown), releases the latch holding the valve 172 in lowered position, such that a spring 182 lifts the valve to closed position. A latch 145, Fig. 9 (not shown), engages a lug 154 to move the motor to its lower inoperative position.

In a semi-conductor device comprising four zones of alternate conductivity types in which one of the outer zones is formed as an annular region in the adjacent inner zone and contacts are made to the two outer zones and to the said inner zone within the annular outer zone, the entire outer line of emergence of the junction between the annular outer zone and the adjacent inner zone is bridged by a sandblasted surface region. As shown, an N-type silicon wafer 2 has a P-type surface region 3, 4 formed by diffusion. An annular gold-antimony foil is alloyed to one surface to produce N-type region 7 contacted by gold-silicon eutectic electrode 8. Simultaneously or subsequently boron-doped gold foils are alloyed to the wafer to form ohmic contacts 5 and 6. The edge of the wafer is removed by grinding or sandblasting to divide the P-type layer into two parts 3 and 4. The device is etched and the surface region 9 surrounding electrode 8 and bridging the junction between regions 4 and 7 is roughened by sandblasting to increase the surface conductivity and hence apply a partial short circuit across the junction without affecting the operation of the gate electrode 6.
